The 21-year-old son of legendary guitarist Eddie Van Halen took to his personal Twitter page where he accused the five-member pop group of insulting him. He offered little explanation as to what exactly ensued although he claims the incident involved Creed guitarist Eric Friedman and drummer Garrett Whitlock.

"Fun fact: Was just insulted by that -----y boy band #OneDirection in the lobby of our hotel this morning! Greetings Birmingham!" Wolfgang tweeted to his 49,000 followers.

"No joke. That ACTUALLY HAPPENED. That group of kids in #OneDirection were d-------- to @IIEROCKII @GWDrums and I," another tweet read.

"They must call themselves that because all of their hair points in #OneDirection," he later tweeted.

The American musician reportedly bumped into One Direction in a hotel lobby where the less than friendly exchange occurred.

One Direction has not publicly responded to Wolfgang's claims and the group is likely more concerned about a more serious issue involving another boy band with the same name.

The U.K.-based group whose members include: Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson, is being being sued for $1 Million by a U.S.-based boy band who claim that the British group stole their name.

The U.S.-based One Direction group members include: lead singer, Sean O'Leary, guitarist, Isaiah Chavez-Pickett, bassist, Scott Nagareda, and drummer, Adam Davis. They claim that their group was formed at least two years ago, and accuses the U.K.'s One Direction of pursuing its group name even after discovering that the name was already taken.

The British group was allegedly made aware that the group name One Direction was already in use when they attempted to file with the U.S. Trademark Office.

"Rather than change their name...they chose to press ahead and come on their tour," the plaintiffs' attorney, Peter Ross, told The Hollywood Reporter. The lawsuit is currently pending.
